TRANSPERINEAL NEEDLE GUIDANCE

摘要

A combined imaging probe holder and interventional needle guide assembly is provided. The imaging probe holder supports an imaging device (e.g., ultrasound probe) in a known relationship with a biopsy/treatment device holder such that a delivery element or interventional needle is constrained within an imaging field of the imaging device.;Constraining the biopsy treatment device within the imaging field allows for real-time monitoring of the biopsy/treatment device during insertion of the interventional needle into patient tissue. In addition, the biopsy/treatment device holder is angularly positionable relative to the image field to allow advancement of the delivery element to any desired location within the imaging field.

1. An system for diagnoses and treatment, comprising:
a probe holder having:
recessed surface sized to receive and secure at least a portion of an ultrasound probe such that an imaging plane of the ultrasound probe is fixed in a known orientation relative to said probe holder; anda rotatable coupling configured for connection with a positioning device, wherein said rotatable coupling permits said probe holder to rotate about a first axis; a guidance having:guide bore configured to receive an interventional needle, wherein a trajectory axis of said guide bore is aligned within the imaging plane of the ultrasound probe when the ultrasound probe is disposed within said probe holder; anda hinge connecting said guide assembly to said probe holder, wherein the hinge permits angular movement of said needle guide assembly relative to said probe holder.
